三一旋挖钻机工法讲座(1)

Working method lecture of SANY rotary drilling rig

随着地下基础行业对旋挖钻机认可度的提高,旋挖钻机的服务对象已经从传统的铁路、公路、桥梁,扩展到工民建、地铁、风电和水利工程等领域。旋挖施工市场扩大后,同时也带来了更多样、更复杂、更具有特性的施工问题。本文介绍了钻进介质为泥质结构和泥质胶结时,旋挖钻机在钻进过程中遇到的问题及解决方案。

With the ground foundation industry has more and more recognition to the rotary drilling rig,the service object of rotary drilling rig also has transferred from traditional railways,roads and bridges, extended to the civil engineering, underground,wind power and hydraulic engineering and other fields.After this rotary drilling and construction market expanded,it brought more diverse,more complex,and more typical construction issues at the same time. This article describes the problems rotary drilling rig encountered in the drilling process and solutions when it in drilling medium are shale structure and clay shale cement.
